1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Pimarane diterpenes represent a notable class of metabolites. Secondary metabolites sphaeropsidin A (SphA) and sphaeropsidin B (SphB), produced by phytopathogenic fungi, have been recently reported for their potential efficacy against bovine coronavirus (BCoV). Hence, for discovering natural antivirals to serve as alternatives to conventional drugs, in this study the efficacy of SphA and SphB during infection with canine coronavirus (CCoV-II) in A72 cell line was examined. Our results demonstrated that a significant reduction in virus yield and in gene and protein expression of viral nucleocapsid protein (NP) was detected in sphaeropsidins (Sphs)-treated infected cells. In infected groups both Sphs enhanced cell viability and improved cellular morphology as well as cytoskeleton rearrangements. Moreover, the protein expression of aryl hydrocarbon receptor (AhR), a strategic modulator of CoVs infection, and of its target CYP1A1, was markedly downregulated in the presence of SphA and SphB during infection. These results were accompanied by a beneficial deacidification of lysosomal environment in infected cells treated with SphA and SphB compared to untreated-infected groups. Overall, our findings demonstrated a promising action of SphA and SphB towards CCoV infection in vitro.
